1. In the Gram Stain procedure, which component acts as the mordant?

• A. Crystal violet
• B. Methyl alcohol
• C. Iodine
• D. Safranin

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

2. A patient's blood pressure is 118/82 mm Hg. The patient asks the nurse, "What do the numbers mean?"? Which is the best reply by the nurse?

• A. "The numbers are within the normal range and are nothing to worry about."?
• B. "The bottom number is the diastolic pressure and reflects the pressure in the arteries when the heart relaxes."?
• C. "The top number is the systolic blood pressure and reflects the pressure of the blood against the arteries when the heart contracts."?
• D. "The concept of blood pressure can be complex. The primary thing to be concerned about is the top number, or the systolic blood pressure."?

Correct answer: C

Rationale: The systolic pressure is the maximum pressure felt on the artery during left ventricular contraction, or systole. The diastolic pressure is the elastic recoil, or resting, pressure that the blood constantly exerts in between each contraction. The nurse should answer the patient's question in terms they can understand and not just say it is normal and there is nothing to worry about. The diastolic pressure is the pressure in the vessels when the heart is at rest, not the stroke volume. Both the systolic and diastolic blood pressure are important. Choice A is incorrect as providing a vague reassurance does not address the patient's query. Choice B is incorrect as it inaccurately describes the diastolic pressure as reflecting stroke volume, which is incorrect. Choice D is incorrect as it oversimplifies the explanation, focusing solely on the top number without providing a complete understanding of blood pressure.

3. Which of the following situations indicates the need to file an incident report?

• A. The neon sign directing parking for visitors has burned out
• B. A nurse must send a syringe pump to maintenance for annual service
• C. A client's blood pressure dropped to 90/55 after receiving a dose of morphine
• D. A client's spouse becomes angry and is asked to leave the premises

Correct answer: D

Rationale: An incident report is necessary for documenting unexpected events that occur in a healthcare setting. Situations that warrant filing an incident report include client accidents, medication errors, security problems, or disruptive behaviors that involve clients, families, or visitors. In this scenario, when a client's spouse displays disruptive behavior and is asked to leave the premises, it is essential to document this incident to ensure a record of the event and its resolution. Choices A, B, and C do not involve disruptive behavior or safety concerns that would require an incident report to be filed.

4. Digestion, elimination, and ___________ are the three functions of the digestive system.

• A. constriction
• B. relaxation
• C. absorption
• D. peristalsis

Correct answer: C

Rationale: The correct answer is 'absorption.' The three main functions of the digestive system are digestion, absorption, and elimination. Absorption refers to the process of absorbing nutrients and other substances from the digested food into the bloodstream. Choices A, B, and D are incorrect: Constriction is not a primary function of the digestive system, relaxation is not a distinct function in this context, and peristalsis is a muscular movement that aids in digestion but is not one of the three main functions of the digestive system.

5. A physician has ordered that a client must be placed in a high Fowler's position. How does the nurse position this client?

• A. The client is placed face-down
• B. The client lies on his back with his head lower than his feet
• C. The client lies on his back with the knees drawn up toward the chest
• D. The client is sitting with the backrest at a 90-degree angle

Correct answer: D

Rationale: A high Fowler's position is a modification of the semi-Fowler's position, in which the client is seated with arms resting at the sides or in the lap. The high Fowler's position requires that the client's head and upper chest are elevated, and the backrest is at a 90-degree angle. This position supports breathing and appropriate chest wall movement, making it easier for the client to breathe. Choices A, B, and C are incorrect because a high Fowler's position involves the client being in a sitting position with the backrest at a 90-degree angle, not being face-down, lying with the head lower than the feet, or lying on the back with knees drawn up towards the chest.
